Answer:
A is the corrrect answer
Step-by-step explanation:
I have done this questiob befor4
3 and 3/4lb=20.25
what you should do is divide both sides by 3 and 3/4 but that isnt nice
convert 3 and 3/4 to improper
3 and 3/4=3+3/4=12/4+3/4=15/4
15/4lb=20.25
times 4/15 to both sides (15/4 times 4/15=60/60=1)
1lb=81/15
1lb=5.4
answer is
1lb=$5.40

*ASSUMING THE ALPHA-LEVELS FOR THESE PROBLEMS IS .05.*
Step-by-step explanation:
8) Left-tailed test means that the alternate hypothesis is x is less than a certain value. The p-value, on the calculator, is normalcdf(-999, -1.83) if it's left-tailed, which is .0336. In that case, we would reject the null hypothesis, because the alpha-level is above our p-value.
9) Two-tailed test means that the alternate hypothesis is x does not equal a certain value. The p-value for this, on the calculator, is normalcdf(1.95,999) times two, because we need both tails. In this case, we would fail to reject the null hypothesis, assuming our alpha-level is .05.
- normalcdf(1.95,999) = .0256*2 = .0512.
